I've been using OPKs to try to time the BDing. There is always a second line on the OPK, but it never seems positive. What's up with that?
The fact is, some women never get a positive OPK, but they are still ovulating. There are two things I will recommend that you try. First, try a different brand of OPK. They vary in sensitivity so you may do well with another brand of test. Second, I recommend that you try testing twice a day. Many women have short LH surge that would be missed if they weren't testing twice a day.
It is common to always see a second line on an OPK. That is because most women always have at least a little bit of lutenizing hormone (LH) in their system.
A third thing you may want to consider is charting. This will help confirm whether or not you are ovulating. It is possible that you are not getting a positive OPK because you aren't getting LH surges and ovulating. If, after a couple months of charting, you find that you are not ovulating - contact your doctor and bring your charts with you to the appointment. Your doctor may be able to help you start ovulating once again.
